I Know There Are A Few More Good Fights But Im Drawing Blanks..i Loved The Tito Fight , But Diego's Fight Had Me On The Edge Of My Seat Going Crazy, And When I Saw The Tooth Go Flying That Was The Clincher

I didn't see GSP vs. Penn, but I can't imagine it was as good as Diego vs. Karo. In fact, I'm hard pressed to find a lot of matches that were as good as that in UFC history. Hands down, this has been the fight of the year so far, but the bigger question to me is which fights in UFC history match up with it? Kimo vs. Gracie would probably be one. Griffen vs. Bonnar. Liddell vs. Belfort? What others do you think?

I THINK KIMO VS GRACIE IS AN OVERRATED FIGHT IMO..FORREST AND BONNAR WAS SICK..BUT I CANT THINK OF A BETTER FIGHT THAN LAST NIGHTS..IT WAS INCREDIBLE..IVE SEEN A FEW SICK FIGHTS IN PRIDE BUT AS FAR AS THE UFC GOES, LAST NIGHTS WAS EASILY TOP 3 IN MY BOOK

Kimo vs. Gracie was over rated as a fight, and I think it just went down as such a legendary fight because it was a real life version of the David Vs. Goliath story and David won. But yeah, the fight itself wasn't anything compared to Diego vs. Karo. I was just throwing out suggestions as to what could compare.

There are a lot better matches then these choices I have seen this year. Loiseau .vs. Franklin was way better than Ortiz .vs. Griffin. But my vote in this poll goes to Penn .vs. St. Pierre. That was a war.
